Abstract: A method includes determining a first taxonomy of an anchor product. The first taxonomy includes a plurality of levels for classifying products organized from a highest taxonomy level to a lowest level. The method further includes determining a second taxonomy closest to the first taxonomy. The second taxonomy is associated with a group of products, the first taxonomy and the second taxonomy have at least a common highest taxonomy level, and the determination is made at least in part based on co-purchase data indicating that the anchor product and at least one product in the group of products are purchased together more often than products associated with other taxonomies are purchased with the anchor product. The method further includes determining a most similar product to the anchor product from the group of products of the second taxonomy and associating the anchor product and the most similar product in a collection.

Abstract: A a plant composite corrosion inhibitor for an oil field and a preparation method thereof belong to the technical field of preparation of oil field chemical agents. The plant composite corrosion inhibitor comprises a first plant ingredient, a second plant ingredient, a corrosion inhibition synergist and an organic solvent. The first plant ingredient is zeaxanthin and a derivative thereof obtained by supercritical CO2 extraction of marigold; the second plant ingredient is prepared from luffa leaves, guava leaves and eclipta according to a mass ratio of 5:8:9; the corrosion inhibition synergist is prepared by mixing potassium iodide, 8-hydroxyquinoline and sodium dodecyl benzene sulfonate according to a mass ratio of 3:4:2; and the organic solvent is ethanol with a mass concentration of 82%. The composite corrosion inhibitor has a good corrosion inhibition effect, and reduces harmful chemical ingredients in the corrosion inhibitor.

The first taxonomy includes a plurality of levels for classifying products organized from a highest taxonomy level to a lowest taxonomy level. The method further includes determining a second taxonomy closest to the first taxonomy. The second taxonomy is associated with a group of products, the first taxonomy and the second taxonomy have at least a common highest taxonomy level, and the determination is made at least in part based on co-purchase data indicating that the anchor product and at least one product in the group of products are purchased together more often than products associated with other taxonomies are purchased with the anchor product. The method further includes determining a most similar product to the anchor product from the group of products of the second taxonomy and associating the anchor product and the most similar product with one another in a product collection.

Abstract: An adjustment mechanism for adjusting height of a support including a through hole and configured to mount a solar panel thereon is provided with a base including an upward extending side plate on a top, a vertical, elongated slot through the side plate, and holes upward oriented, equally spaced apart from the slot in which a lower portion of the support is engaged with each side plate; an adjustment plate including at least one peg on an inner surface and a central opening in which each peg is configured to fit into one hole; and a threaded fastener driven through the central opening, the slot and the through hole to adjustably fasten the adjustment plate, the side plate and the support together.

Abstract: Systems and methods for providing suggestions of complementary products responsive to an anchor product are disclosed. The method includes receiving a selection of an anchor product. A similarity score between text embeddings of the anchor product and text embeddings of a plurality of products in a product database is calculated. A similarity score between an image feature of the anchor product and an image feature of the plurality of products in the product database is calculated. A weighted score between the two similarity scores as calculated for the anchor product and the plurality of products in the product database is calculated. At least one of the products from the product database having a highest weighted score is selected and returned responsive to the selection of the anchor product.

Abstract: This disclosure includes systems and methods for providing accessory product recommendations to a user that may include items related to an anchor product selected by the user. The determination of accessory product recommendations may be made based on compatibility between anchor and accessory products, based on manually entered anchor-accessory product relationships, using an algorithm trained to determine anchor-accessory product relationships, or using other methods. The accessory recommendations may be provided along with the anchor product on an electronic user interface, such as a website, in response to the user's selection of the product through the electronic user interface. In this way, the accessory and anchor products may be viewed and/or selected by the user with a minimal number of clicks or user interactions through the electronic user interface.

Abstract: A fastener for a corrugated sheet includes a cylindrical assembly including elongated, plate shaped fastening members assembled as a hollow cylinder. Each fastening member is tapered to one end to form a hook at one end and having a curved groove on an outer surface, and a curved trough on the outer surface at the other end of the fastening member. The curved troughs are assembled to form an annular recess. A retainer ring is secured to the annular recess. A ring-shaped elastic member is secured to the curved groove. A first sealing member is put on the retainer ring. A threaded bolt driven through a washer, the retainer ring, and the fastening member. An expansion nut has a multi-sided outer surface and is moveably secured to the threaded bolt.
